Thanks

Miles: 82,000
Oil Ash Volume: 90ml
Oil Type: 1-80k miles: OEM Castrol 80k changed to Mobil 1 ESP
Avg. MPG: 34mpg

***Virtually every tank since about 10k miles has had OptiLubeXPD.

This car is a kids taxi, lots of off/on/off, short trips. Several extended long roadtrips, and weekend "Italian tune-ups" to help clean things out. In town, I get right at EPA 30mpg, highway can still see 45mpg

I was expecting more ash than this, as I know TDIs prefer steady-state highway cruising. Some here predicted early DPF clogging, but so far, so good!

Our 100K Follow-up:

Model Year: 2009
Model: Jetta Sportwagen
Tranny: 6M
Miles: 100,999
Oil Ash Volume: 99
Oil Type: Mobil 1 ESP (since 30K)
Avrg. MPG: 38

Wife took over the wagon and the mileage accumulation has slowed somewhat. MPG has dropped off too. I stopped watching it quite some time ago, but the last 2000 miles showed 39 MPG. So I'd safely say she's getting 38 MPG. Lots more short (15-30 mile) trips than when I was taking it to the airport on a regular basis.

Well, add up another DPF failure on my 12 Jetta at 27k miles. I'll see if I can get a printout of the data log.
